Right shoulder paind down to fingers

A couple of days ago, my right hand was just throbbing. It hurt to move & grab anything. I could not figure out why it hurt or how I would have injured it. It stopped hurting by the following morning. Later that day, I felt a strange, shaky feeling and a little short of breath. 2 days later, all of a sudden I am having throbbing shoulder pain in my right arm, hurts really bad in my shoulder blade - hurts constantly but much more if I lift my arm or move (roll in bed for example). It hurts all the way down my arm, to my fingertips. I am also a little short of breath. Tried taking Aleve, Tylenol, Motrin, iced shoulder - nothing is helping. My fingertips are tingling. Not sure what is going on, but really do not like this feeling and getting nervous!
